Upon any exercise of the Warrants prior to effective registration for resale or except as in accordance with Rule 144 under the Securities Act, certificates representing the Warrant Shares shall bear a restrictive legend substantially identical to that set forth as follows: "The securities represented by this certificate have not been registered under the Securities Act of 1933, as amended, or the securities laws of any state (collectively, the "Acts"). Neither the shares nor any interest therein may be offered, sold, transferred, pledged, or otherwise disposed of in the absence of an effective registration statement with respect to the shares under all of the applicable Acts, or an opinion of counsel satisfactory to U.S. Energy Corp. to the effect that such registrations are not required."

ARTICLE III Anti-Dilution Provisions ------------------------ 3.1 Adjustment of Exercise Price and Number of Warrant Shares. The ------------------------------------------------------------- Exercise Price and number of Warrant Shares shall be subject to adjustment from time to time as hereinafter provided in this Article III. No other adjustments to the Exercise Price or the number of Warrant Shares shall be made, for any reason. (a) Exercise Price Adjustments. The Exercise Price shall be subject to -------------------------- adjustment from time to time as follows: (i) Adjustment for Stock Splits and Combinations. If the Company ------------------------------------------------- shall, at any time or from time to time after the date hereof (the "Original Issue Date") while this Warrant remains outstanding, effect a --------------------- subdivision of the outstanding Common Stock, the Exercise Price in effect immediately before such subdivision shall be proportionately decreased. Conversely, if the Company shall at any time or from time to time after the Original Issue Date combine the outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately before such combination shall be proportionately increased. Any adjustment under this Section 3.1(a)(i) shall become effective at the close of business on the date the subdivision or combination becomes effective. (ii) Adjustment for Reclassification, Exchange, and Substitution. If ------------------------------------------------------------ at any time or from time to time after the Original Issue Date while this Warrant remains outstanding, the Common Stock is changed into the same or a different number of shares of any class or classes of stock, whether by recapitalization, reclassification or otherwise, the Registered Holder shall have the right thereafter to convert such stock into the kind and amount of stock and other securities receivable upon such recapitalization, reclassification or other change by holders of the maximum number of shares of Common Stock into which such shares of Common Stock could have been converted immediately prior to such recapitalization, reclassification or change. (iii) Reorganizations, Mergers, Consolidations, or Sales of Assets. ------------------------------------------------------------- If at any time or from time to time after the Original Issue Date while this Warrant remains outstanding, there is a capital reorganization of the Common Stock, provision shall be made so that the Registered Holder shall thereafter be entitled to receive upon exercise hereof the number of shares of stock or other securities or property of the Company to which a holder of the number of shares of Common Stock deliverable upon exercise immediately prior to such event would have been entitled as a result of such capital reorganization. (iv) Rounding of Calculations; Minimum Adjustment. All calculations --------------------------------------------- under this Section 3.1(a) shall be made to the nearest cent. Any provision of this Section 3.1 to the contrary notwithstanding, no adjustment in the Exercise Price shall be made if the amount of such adjustment would be less than one percent. (v) Timing of Issuance of Additional Common Stock Upon Certain ------------------------------------------------------------------ Adjustments. In any case in which the provisions of this Section 3.1(a) ----------- shall require that an adjustment shall become effective immediately after a record date for an event, the Company may defer until the occurrence of such event issuing to the Registered Holder after such record date and before the occurrence of such event the additional shares of Common Stock or other property issuable or deliverable upon exercise by reason of the adjustment required by such event over and above the shares of Common Stock or other property issuable or deliverable upon such exercise before giving effect to such adjustment; provided, however, that the Company upon request -------- ------- shall deliver to such Registered Holder a due bill or other appropriate instrument evidencing such Registered Holder's right to receive such additional shares or other property, and such cash, upon the occurrence of the event requiring such adjustment. (b) Statement Regarding Adjustments. Whenever the Exercise Price ------------------------------- shall be adjusted as provided in Section 3.1(a), and upon each change in the number of shares of the Common Stock issuable upon exercise of this Warrant, the Company shall thereafter give notice thereof to the Registered holder, with a statement showing in detail the facts requiring such adjustment and the Exercise Price and new number of shares issuable that shall be in effect after such adjustment'. 3.2 Costs. The Registered Holder shall pay all documentary, stamp, ----- transfer or other transactional taxes attributable to the issuance or delivery of the Warrant Shares upon exercise of this Warrant. Additionally, the Company shall not be required to pay any taxes which may be payable in respect of any transfer involved in the issuance or delivery of any certificate for such Warrant Shares. The Registered Holder shall reimburse the Company for any such taxes assessed against the Company. 3.3 Reservation of Shares. The Company shall reserve at all times so ----------------------- long as this Warrant remains outstanding, free from preemptive rights, out of its treasury Common Stock or its authorized but unissued shares of Common Stock, or both, solely for the purpose of effecting the exercise of this Warrant, sufficient shares of Common Stock to provide for the exercise hereof. 3.4 Valid Issuance. All shares of Common Stock which may be issued --------------- upon exercise of this Warrant will upon issuance by the Company be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges with respect to the issuance thereof attributable to any act or omission by the Company, and the Company shall take no action which will cause a contrary result (including without limitation, any action which would cause the Exercise Price to be less than the par value, if any, of the Common Stock). 'ARTICLE IV Covenant of the Company ----------------------- The Company covenants and agrees that this Warrant shall be binding upon any corporation succeeding to the Company by merger or consolidation'. ARTICLE V Miscellaneous ------------- 5.1 Entire Agreement. This Warrant and the Registration Rights ----------------- Agreement contain the entire agreement between the Registered Holder and the Company with respect to the Warrant Shares that it can purchase upon exercise hereof and the related transactions and supersedes all prior arrangements or understanding with respect thereto. 5.2 Governing Law. This Warrant shall be governed by and construed in -------------- accordance with the internal laws of the State of Wyoming, without regard to its conflict of law provisions. Any litigation shall be conducted in the courts of the State of Wyoming, or the United States District Court for Wyoming or Colorado. 5.3 Waiver and Amendment. Any term or provision of this Warrant may be -------------------- waived at any time by the party which is entitled to the benefits thereof, and any term or provision of this Warrant may be amended or supplemented at any time by the written consent of the parties (it being agreed that an amendment to or waiver under any of the provisions of Article III of this Warrant shall not be considered an amendment of the number of Warrant Shares or the Exercise Price). No waiver by any party of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, shall be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising because of any prior or subsequent such occurrence. 5.4 Illegality. In the event that any one or more of the provisions ---------- contained in this Warrant shall be determined to be invalid, illegal or unenforceable in any respect for any reason, the validity, legality and enforceability of any such provision in any other respect and the remaining provisions of this Warrant shall not, at the election of the party for whom the benefit of the provision exists, be in any way impaired. 5.5 Copy of Warrant. A copy of this Warrant shall be filed among the ----------------- records of the Company. 5.6 Notice. Any notice or other document required or permitted to be ------ given or delivered to the Registered Holder shall be delivered at, or sent by certified or registered mail to such Registered Holder at, the last address shown on the books of the Company maintained at the Warrant Office for the registration of this Warrant or at any more recent address of which the Registered Holder shall have notified the Company in writing.

Upon receipt of ------------------------------------------------- evidence satisfactory to the Company (an affidavit of the Registered Holder shall be satisfactory evidence) of the loss, theft, mutilation or destruction of this Warrant, and, in the case of any such loss, theft or destruction, upon delivery of a bond of indemnity in such form and amount as shall be reasonably satisfactory to the Company, or, in the event of such mutilation upon surrender and cancellation of this Warrant, the Company will make and deliver a new Warrant of like tenor, in lieu of such lost, stolen, destroyed or mutilated Warrant; provided, however, that the original Registered Holder of this Warrant -------- ------- shall not be required to provide any such bond of indemnity and may in lieu thereof provide his agreement of indemnity. Any Warrant issued under the provisions of this Section 6.8 in lieu of any Warrant alleged to be lost, destroyed or stolen, or in lieu of any mutilated Warrant, shall constitute an original contractual obligation on the part of the Company. This Warrant shall be promptly canceled by the Company upon the surrender hereof in connection with any exchange or replacement.
